Co-authored-by: @awkwardbunny This PR adds a Debian package registry. You can follow [this tutorial](https://www.baeldung.com/linux/create-debian-package) to build a *.deb package for testing. Source packages are not supported at the moment and I did not find documentation of the architecture "all" and how these packages should be treated. ![grafik](https://user-images.githubusercontent.com/1666336/218126879-eb80a866-775c-4c8e-8529-5797203a64e6.png) Part of #20751. Revised copy of #22854. --------- Co-authored-by: Brian Hong <brian@hongs.me> Co-authored-by: techknowlogick <techknowlogick@gitea.io> Co-authored-by: Giteabot <teabot@gitea.io>
